SLUG-CASTING macmn. r

To all whom it may concern:

Be it known that I, VVILLIAM C. L1nBnR- KNECHT, a citizen of the United States, re-

siding at Bisbee, in the county of Cochise and State of Arizona, have invented certain new and useful Improvements in Slug-Casting Machines, of which the following is a specification, reference being had therem to the accompanying draw ing.

My invention relates to typographical machines, such asli notype machines of the general organization represented in United States Letters Patent to O; Mergenthaler, No. 436532, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print, and then. assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started. After the slug is cast, it is delivered from the mold by an ejector which advances from the rear and moves it forwardly out of the mold and into a receiving galley.

It frequently happens that the slug is cast with type characers extending only partly along its edge, the remaining portion being left plain. This is particularly true in tabular work and the like, wherein very short lines are employed. It has been found that when printing from such slugs, the ink sometimes finds its way onto the plain portions and is impressed or carried on to the paper, resulting in the smearing or blurring of the printed matter.

' My invenion is intended to avoid the above objection and aims to produce a slug reduced or recessed beyond the type characters so that its plain portion will stand well be low the printing surface when the slug is assembled in a form, thus obviating any possibility of the ink becoming lodged upon the plain portion of the slug or of being attain this object by providing one of the mold liners with a longitudinally extending strip or member which projects into the mold slot at the front to partially fill the same and which will yield before the slug Specification of Letters Patent.

as it is ejected from the mold. However, my invention is not restricted to the particularuse above described, as it is apparent that there may be many instances Where it will be desirable to cast recesses in the edges.

of the slugs, and without regard to whether they be formed with or without type characters. Thus, it may be desired in some cases to cast slugs withplain reduced or recessed portlons to receive and support a cut or printing plate, while inother cases it may be desired to cast plain low quads to be inserted between the lines, which last result may be readily secured by simply extending the strip entirely across the mold slot. T have herein shownmy invention merely in preferred form andby way of example, and obviously many changes and variations may be made therein which will be comprised within its spirit. I therefore desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations, are specified in the claims.

Referring to the drawings: Figure 1 is a perspective View of a portion of a linotype machine having my invention applied thereto; Fig. 2 is a longitudinal section.

taken through the mold and adjacent parts,

and showing an assembled line of matrices tached; and Fig. 5 shows a slug produced in accordance with my invention.

The mold A is mounted upon the rotatable disk B, which presents it first in the casting position, where it is closed at the front by the composed line of matrices X confined between the-clamping jaws G and G, as shown in Fig. 2, and subsequently carries it to the position shown in Fig. 1, when the cast slug Z is removed from the mold by an ejector blade 0, which advances from the rear and carries the slug forwardly between a pair of trimming knives D and delivers it to a receiving galley E, wherein the slug, is assembled along side a preceding slug or against the resistant E by the stack ing device F. The mold A comprises as usual the body portion A and the cap A constituting the side walls of the mold slot,

and the two intermediate fixed liners A constituting its end walls. lihe left wall proper of the slot, however, is ordinarily constituted by the adjustable liner A, which can be set in different longitudinal positions therein to vary the length of the slugs. The parts so far described, except as hereinafter pointed out, are or may be of the'regular construction.

' In accordance with my invention, the adjustable liner A is provided at its front edge with a longitudinal strip or member A projecting beyond itsinner or operative end so as to fill the mold slot partially at the front, it being noted that in the present instance the strip does not extend throughout the, full length of the slot but terminates therein to one side of those matrices having the formative cavities X, as clearly illus trated in Fig. 2. As a result of this construction, the slug Z is cast in the form shown in Fig. 5, having a type carrying surface Z and a recess Z located beyond it.

Since the slug Z is ejected forwardly from the mold, itis apparent that some prgvision should be made to remove the strip A from its outgoing path, and to this end the strip is pivotally connected to the liner A, as at A, so as to be swung outwardly by the slug as it is ejected, in the manner indi cated in Fig. 1. After the slug passes the strip, it will ordinarily, fall back into place, but in order to insure its return, there is provided a spring A located within a curved recess A of the liner and bearing against the short arm A of the strip, the outer wall of the recess being concentric with the axis A so as to permit the movement of the arm during the swinging. of the strip as just described.

Because of its attachment to the liner A, the longitudinal position of the strip will be altered by the adjustment of the liner, so

that a recess Z will be formed in the slug whether the latter be of the length shown in Fig. 5, or of the length shown in Fig. 1. However, such adjustment of the liner will not alter the extent of projection of the strip into the mold slot, and consequently the length of the recess Z will not be varied. Should that become desirable or necessary, the strip may be removed from the liner and replaced by another of different length, it being detachably connected to the liner for this purpose, as shown in Fig. 4. By thus interchanging the strips, slugs may be produced with recesses of any desired length. If a strip projecting entirely across the mold slot'be employed, a plain low slug or quad will result.

As previousy stated, I have shown my invention merely in preferred form and by way of example, and it should be understood that many changes and variations maybe made therein and in its mode of application without departure from its scope. For

instance, it is not essential that the strip A should be carried by an adjustable liner, nor that it be used to produce a recess the slug at its left end, since it would be practicable to connect the strip to a fixed part of the mold,-or to arrange it so as to produce a recess at the right end of the slug. Such modificationswill readily suggest themselves to those skilled in the art.

Having thus described my invention, its construction and mode of'operation, what claim and desire to secure by Letters Patent of the United States is as follows:

1. In a slug casting machine, the combinatached strip or member projecting into the mold slot and only partially filling the same at the front, so as to produce a recess along the upper edge of the slug cast in the mold. 3'.
